Filed: 1981-01-12
Abstract: PURPOSE:To obtain sufficient artificial-color reducting effect, by providing space frequency characteristics so that the space frequency amplitude attenuation effect of a diffraction grating type space frequency characteristic control filter is maximized to green light in visible light range. CONSTITUTION:A birefringence plate and a diffraction grating type space frequency characteristic cotrol filter are provided on an image pickup optical path and light from an object is polarized to reduce the space frequency amplitude attenuation effect of the birefringence plate. In this case, when characteristics which maximize the effect of said control filter to green light, artificial chrominance signal reduction effect is obtained while high resolution is maintained in a luminance band. For outdoor image pickup operation, an artificial chrominance signal preventing method effective to polarized green light G is realized by using said control filters in combination and the effect of the control filter for red light R and blue light B is minimized.

IPC: F02C6/18
Filed: 1994-01-18
Abstract: PURPOSE:To enable optimal load distribution in relation to a unit load command at all times by setting a difference between a GT load command signal on the basis of a GT load restricting amount and GT load upper limit amount by atmosphere temperature and a unit load command signal as a boiler load command signal. CONSTITUTION:A unit load command is inputted from an outside into a memory 1, an operating range is restricted by an upper/lower limit setting apparatus 2. A distribution ratio between gas turbine (GT) output and boiler output in each atmosphere temperature is restricted by a function generator 4 so as to increase a unit efficiency in the restricting range of a boiler as larger as possible. A signal which is generated by a multiplication apparatus 5 and a signal which is regulated maximum output of GT in each atmosphere temperature by a function generator 6 are compared and selected with each other by a selector 7 so as to form a final GT load command signal. A boiler load command signal for correcting the regulating amount of GT output is generated from a unit load command signal and a final GT load command signal in a subtracter 6. It is thus possible to enable optimal load distribution.
